To all whom it may concern.-

Be it known that I, JOHN P. KIRK, team.

of the United States, and a residentof Austin,

,in the county of Travis and State of Texas,

have invented certain new and useful Improvements in Car-Couplings; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled'in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

Figure 1 of the drawings is a representation of the invention, partly in section, and applied to a car. Fig. 2 is a plan View of the same; and F1g. 3 is a plan View of the link.

This invention has relation to certain new and useful improvements in car couplings, and 1s designed to provide a simple, efficient' and practical device of such character as to readily couple by impact, and capable of uncoupling without the necessity of going between the cars.

With this object in View the invention consists in the novel construction and combinatlon of parts, all as hereinafter described, and

. pointed out in the appended claims.

Referring to the accompanying drawings illustrating the invention, the letter A designates the draw-head, B the coupling link, and O the pin. The pin 0 is of the usual construction, and attached to its upper end is a.

chain D, or other flexible connection. The upper end of the chain or connection is attachedfto the upper portion of a-sectorE which is rigidly attached to a transverse rockshaft or rod F supported in bracket bearings lel, or nearly so, with the said cranks. The object of this arrangement is to permit the extremities of the cranks, and the upper corner portion of the sector at b, to rest against the end of the car, when the coupling is raised and the sector in the position shown by the dotted lines in Fig. 1 thus forming a stop to prevent the pin from being raised too high, and at the same time leave the sector, rockshaft-or rod, and the pin in position to be easily thrown down by impact.

side or rim of the sector is grooved, or other-- wise suitably arranged, so that the chain or connection D will keep in its proper place.

The link B is like the form in ordinary use except that it is weighted at one end, as shown at K, by making it both thicker and longer. The draw-head is provided with an upward transverse beveled projection M on the lower wall of the forward portion of the draw-head chamber. The weighting of the link, causes it, when in place in the draw-head, to always assume anearly horizontal position although free to move with the motion of the cars.

The outer The act of uncoupling is accomplished by Q going to the corner of the car and turning the crank of the rock-shaft, or red, back until it rests against its stop, which as above described is preferably the end of the car, although other suitable means might be provided. The uncoupling is preferably done at the light end of the link, otherwise it is necessary to reverse the link in the draw-head before making another coupling. 3 a

When coupling is made, the impact of the cars causes the sector to fall, and the pin to drop through the link in the ordinary manner.

Having thus described my invention, what I claim as-new, and desire to secure by Letters Patent, is-

1. Ina car coupling, the combination with a drawhead having a transverse upward shoulder projection on the lower face of the forward portion of its chamber, of a link havinga weighted endseating behind said projection, substantially as specified. I
